Topic 1 IML Introduction to IS & Management Introduction to Information Systems and Management - Concept - Information System - Management Information System □ Information System An information system can be defined technically as a set of interrelated components that collect (or retrieve), process, store and distribute information to support decision making and control operation in an organisation. Information systems may also help managers and workers to analyse problems, to visualise complex subjects and to create new products. Information mean data that have been shaped into a form that is meaningful and useful to human beings. Data, in contrast, are streams of raw facts representing events occurring in organisations or the physical environment before they have been organised and arranged into a form that people can understand and use. There are three main activities in an information system: - Input captures or collects raw data from within the organisation or from its external environment. - Processing converts this raw input into a more meaningful form. - Output transfers the processed information to the people who will use it or to the activities for which it will be used.

Prof. Computer Science, SUB Page: 1 Topic 1 IML Introduction to IS & Management □ Management Information System Management information system (MIS) deals with the planning for, development, management, and use of information technology tools to help people perform all tasks related to information processing and management. Three key resources in MIS are: - Information - Information technology - People □ Organisations and IS Information systems and organisations influence one another. Information systems must be aligned with organisation to provide information within the organisation. At the same time, the organisation must be aware of and be open to influence of information systems in order to benefit from new technologies. An organisation is a stable, formal social structure that takes resources from the environment and processes them to produce outputs. Common features of an organisation include: - Standard Operating Procedure (SOP) - Organisational Politics - Organisational Culture Information systems have become integral, online, interactive tools deeply involved in the minute-to-minute operations and decision making of large organisations. The formal organisational unit or function responsible for technology service is called the Information System Department. The information system department is responsible for maintaining the hardware, software, data storage, and networks that comprises the firm’s IT infrastructure. Six major types of information systems are: - Executive Support System (ESS) - Management Information System (MIS) - Decision Support System (DSS) - Knowledge Work System (KWS) - Office System - Transaction Processing System (TPS) Prepared by Jamir Ahmed, Asst.
